Abstract: TRAILER STEERING DEVICE FOR SPACED AXLE TRAILER          ABSTRACT:        A steering device for steering a spaced axle trailer includes a pair of pivots connecting a tongue to a frame of the trailer.  The steering device includes a primary arm pivotally connected to the trailer frame,  The primary arm is coupled to pivotal spindle mechanisms on which the front trailer wheels are mounted to translate pivotal movement of the primary arm to the spindles, causing steering of the trailer.  A mechanical surge brake device is connected to the tongue.  A laterally movable element of the surge brake mechanism is attached to a hitch socket that fits over a hitch ball attached to a tow vehicle, so that the distance between the tow vehicle and the trailer is decreased slightly when the brakes of the tow vehicle are applied, First and second tensile control elements are connected between first and second spaced points of the primary arm and first and second spaced control connecting points of the tow vehicle to apply tensile forces to the primary steering arm, causing it to pivot in response to changing of direction of the tow vehicle relative to the trailer.

Abstract: ABSTRACT OF THE DISCLOSURE      A tool and method for pressure forming teeth on the periphery of a cylindrical work piece wherein each of the teeth has a predetermined crown formed thereon.  The tool includes a body having a leading edge and a trailing edge. The leading edge. of the tool body has an undercut surface thereon supportingly receiving a tooth crowning section having the side edges thereof shaped outwardly of the undercut surface on the tool to shape transversely formed insert teeth to form a predetermined crown on the teeth of the part being formed by the tool.  In one method, pre-formed teeth on a rack insert. are formed by a grinding tool following a straight path; the insert for forming the crown on the rolled part then is held on a grinding fixture base by a center shim so as to form a concave surface on the underside of the insert by exceeding the modulus of elastici-ty of the rack insert material wherein, following removal of the insert from the grinding fixture base, the teeth sur-faces on the rack insert are shaped in a convex form to produce crowning of spline teeth on a cylindrical member that is pressure formed by the insert.

Abstract: ABSTRACT OF THE DISCLOSURE        A fluid dispensing applicator for crease setting compositions comprises a support, a reservoir slidably mounted on the support, an applicator nozzle connected to the reservoir to deliver fluid therefrom, and a bearing element movable relative to the support between retracted and advanced positions capable of effecting slidable movement of the reservoir respectively towards and away from the support when so moved.  A rotatable member is mounted on the support and is geared to a piston arrangement for urging fluid from the reservoir through the nozzle.  The nozzle, bearing element and the periphery of the rotatable member are aligned on the same side of the applicator.  When the applicator is not in use a combination of the pressure within the reservoir and gravity cause the bearing element to move the reservoir into the retracted position thereby relieving the pressure in the reservoir and preventing oozing of crease setting compostion from the nozzle.

Abstract: BRAKING METHOD AND APPARATUS FOR VIBRATORY FEEDER     ABSTRACT         A material dispensing apparatus including drive means for driving a feeder bowl is disclosed.  A control circuit for controlling the drive includes a Hall effect amplitude sensing transducer for monitoring the magnitude of bowl vibrations and a braking circuit for controlling the damping of vibratory motion after the requisite amount of material has been fed from the feeder bowl.  The braking circuit selectively reverses the current flow through a drive coil which comprises a portion of the drive circuitry of the apparatus.  This current reversal disrupts the rhythm of forced oscillations which feed material from the bowl and causes bowl motion to be damped.  A mechanical brake coupled to the bowl complements the braking action of braking circuit and locks the bowl in place to prevent accidental dispensing of parts.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention relates to a device for the repetitive copying of originals in a copier and comprises a pivotable separating guide which forms, with a supplementary guide-plate, a loop-compartment for the copying original, the front edge of which is gripped and guided by a gripping unit. The separating guide is composed of planar portions which adjoin one another at an obtuse angle and give the separating guide a shape which is generated by a series of discrete bends.  Air nozzles direct streams of air into the loop-compartment in such a manner that during the repetitive copying process they press the copying original, which is present in the loop-compartment, against the interior surfaces of the separating guide and of the curved supplementary plate.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus is provided herein for cutting fish heads into at least two parts.  The apparatus includes guide means including an elongated head supporting rail.  Means are provided for consecutively moving the fish heads, which have been threaded onto the head supporting rail, along the rail.  Gill separating means are mounted on the head-supporting rails for engaging with the gills of the fish heads being passed along the supporting rail, so as to separate the gills from the fish heads at least at one end of the gills.  Cutting means extend into the path of movement of the fish heads so as longitudinally to cut the respective fish heads passing the cutting means, whereby more valuable fish head parts may be separated from less valuable fish head parts.  By this apparatus, then, the separation of the various parts of the fish head is achieved without manual cutting, so that utilization of fish heads for human consumption is now economic.

Abstract: ABSTRACT OF THE DISCLOSURE    A nuclear reactor fuel element having improved heat transfer between fuel material and cladding is described.          The element consists of an outer cladding tube divided into an upper fuel section containing a central core of fission-able or mixed fissionable and fertile fuel material, slightly smaller in diameter than the inner surface of the cladding tube and a small lower accumulator section of the cladding tube being which is filled with a low molecular weight gas to transfer heat from fuel material to cladding during irradiation. A plurality of essentially vertical grooves in the fuel section extend downward and communicate with the accumulator section. The radial depth of the grooves is sufficient to provide a thermal gradient between the hot fuel surface and the relatively cooler cladding surface to allow thermal segregation to take place between the low molecular weight heat transfer gas and high molecular weight fission product gases produced by the fuel material during irradiation.  The fission product gases migrate to the cooler cladding surface of the groove and descend by gravity into the accumulator section, while the low molecular weight remain in the fuel section, thus reducing diminution of the heat transfer properties of the low molecular weight gas. The accumulation may also contain gettering material to sorb certain high molecular weight gases to prevent their reentering the fuel section when the fuel element is cold.
